MECHANICAL TOY.

Application filed November This invention relates to mechanical toys ofthe kind in which movable means or 1nstruinentalities are provided on aWheeled body, in combination with operating means, whereby the movablemeans or instrumentalities will be actuated in the desired manner whenthe toy is pulled or propelled along the floor.

Generally stated, the object of the invention is to provide a novel andimproved construction whereby one or more knockers are provided on awheeled base or body, in combination with operating means, operated byone or more of the wheels of the body, and in combination with means tobe engaged by said knocker or knockers, thereby to produce a drummingnoise or effect, so to speak, when the toy is pulled or propelled alongthe floor.

To the foregoing and other useful ends, the invention consists in thematters hereinafter set forth and claimed, and shown in the accompanyingdrawings, in which,

Fig. 1 is a plan of a mechanical toy embodying the principles of theinvention.

Fig. 2 is a longitudinal section of said toy, on line 2-2 in Fig. 1.

As thus illustrated, the invention comprises a sheet-metal body 1 havinginclined and oppositely disposed surfaces 2 facing forwardly andrearwardly. Wheels 3 of any suitable character are provided to supportthe body. An axle having cranks a is provided for the wheels 3 at oneend of the toy, preferably at the rear end. At about the middle of thetoy, a transverse cylindrical support 5 is provided below the horizontalwall 6 of the body. Rods 7 extend downwardly through slots 8 in the'wall6, and are bent around the member 5, m the manner shown. The upper endsof these rods have balls 8 thereon to engage the surfaces 2 previouslymentioned. The lower end portions 9 of the rods are connected by pitmen10 with the cranks 4 previously mentioned. Any suitable means can beemployed for propelling the toy along the floor, such as the cord 11hitched to the front end of the toy. Thus, when the toy is pulled alongthe floor, the cranks 4 will actuate the pitmen 10 and thereby vibratethe rod 7 back 9, 1925. Serial No. 67,816.

and forth, causing the balls 8 to hit first one surface 2 and then theother, and thus produce a pounding or drumming noise. As shown, twoknockers 8 are employed, producing the knocking or drumming noise, butit is obvious that any suitable or desired number of knockers can beemployed without departing from the spirit of the invention.

Without disclaiming anything, and without prejudice to any noveltydisclosed, what I claim as my invention is:

1. In a mechanical toy, the combination of a wheeled body, a knockeroperative to vibrate back and forth, front and rear portions of saidbody constructed and disposed in position to form opposite stops toreceive the impacts of said knocker to produce a pounding or knockingsound, and wheeloperated means for actuating said knocker from one stopto the other when the toy is propelled along the floor.

2. A structure as specified in claim 1, said body comprising an inclinedsurface upon which the knocker engages, at one end of the toy, and anoppositely inclined surface at the other end of the toy, forming saidstops, the knocker vibrating between the two surfaces, and alternatelyengaging with resounding impacts first One and then the other.

3. A structure specified in claim 1, there being a plurality of saidknockers, and said body having oppositely disposed surfaces be tweenwhich the knockers are disposed, ifolfllllllg said stops, so that eachknocker eugages with recounding impacts first one surface and then theother.

at. A structure as specified in claim 1. said knocker comprising a rodpivoted to vibrate about a transverse axis disposed substan tially atthe middle of the toy, so that the knocker swings between the front andrear end; of the toy, the said body having oppositely disposed surfacesbetween which the knocker operates forming said stops, and said meansfor operating the knocker comprising a crank axle connected by a pitmanto the lower end of the rod.

Specification signed this 5th day of Nov.
